Gerald Robotnik

Professor Gerald Robotnik (プロフェッサー・ジェラルド・ロボトニック Purofessā Jerarudo Robotonikku?) is a character in the anime series Sonic X. He is the grandfather of Dr. Eggman's and Maria Robotnik. He is a world-renowned scientist who experiments with unique discoveries mainly at Space Colony ARK.

Many years ago, Gerald created Space Colony ARK, trying to develop the Ultimate Life Form. After the Biolizard, he finally created the Ultimate Life Form, Shadow the Hedgehog. It is unknown if he created Shadow with Black Doom or not. However, Maria died trying to protect Shadow from GUN (although in the dub, they took her away.), because the military feared Gerald would use it to take over the world. Gerald was then imprisoned at Prison Island, taking on a new purpose: get revenge. He was able to compel Shadow into getting revenge on Earth. He was found out and executed, but not before creating a video revealing his plan when all seven Chaos Emeralds were put into theEclipse Cannon.
